rebeccamycin analog in treating patients with metastatic or locally recurrent colorectal cancer

Conditions: Colorectal Cancer

Summary: phase ii trial to study the effectiveness of rebeccamycin analog in treating patients who have metastatic or locally recurrent colorectal cancer. drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die.

objectives: i. determine the objective response rate of patients with metastatic or locally recurrent colorectal cancer treated with rebeccamycin analogue. ii. determine the toxicity of this regimen in this patient population. iii. determine the effect of this regimen on progression-free and overall survival in these patients. outline: this is a multicenter study. patients receive rebeccamycin analogue iv once on day 1. treatment repeats every 21 days for a maximum of 12 courses in the absence of unacceptable toxicity or disease progression. patients are followed every 3 months for 2 years, every 6 months for 3 years, and then annually thereafter.
